GAGE FOR SHOE-MACHINES.

SPECIFICATION formin part of Letters Patent No. 640,064, dated December26, 1899.

Application filed April 29 1899.

T all whom it may concern.-

Be it known that I, ERASTUS E. WINKLEY, a citizen of the UnitedStates,residing at Lynn, in the county of Essex and State ofMassachusetts, have invented certain new and useful Improvements inAutomatic Gages for Shoe- Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

The present invention relates to improvemerits in gages for machines foroperating on shoe-soles-such, for example, as shoe-sewing machines andsole-trimming machinesineluding such machines as are commonly known asrough-rounding? and channeling machines. In all machines of this classthere is provided a tool or toolssuoh, for example, as the needle of thesewing-machine or the rounding-knife and channeling-knife of a roundingand channeling machine which are required to operate upon the sole ofthe shoe along a path bearing a certain relation as to its location tothe edge of the last in the shoe to be operated upon, and it is requiredfor many styles of shoes such, for example, as Scotch edge orBaltimoreedge sl1oes--to vary the position of this path with relation tothe edge of the last.

In the prior art, both in the class of sewing- Inachines and roundingand channeling machines, there have been provided movable gages wherebythe above-suggested result could be accomplished. Such gages, however,in so far as I am advised of the state of the art, have either beenmoved from their retracted to their advancedposition by hand or byautomatic mechanism which during a singlecycle of operation bothadvanced and retracted such gage, the retracting movement following theadvancing movement without any interference on the part of the operatorand at a time which was independent of his control.

The hand-operated device above referred to has been found to beuncertain and not uniform in its operation, its use requiring theexercise of the greatest care and judgment on the part of the operator,and the automatic device above referred to, while capable of successfuloperation on certain sizes and Serial No. 714,989. (No model.)

styles of shoes, requires change of parts to adapt it for variations insize and style and complicated adjustments which render the devicedifficult to use by the ordinary shoefactory operator.

It is the object of the present invention to provide a movable gage formachines of the types hereinbefore mentioned with automatic mechanismfor operating such gage, such mechanism being normally inactive when thegage is in its retracted and advanced positions, and to provide suitablemeans under the control of the operator whereby the gageoperatingmechanism may be brought into operation at the desired times to eitheradvance or retract such-gage.

To the above end the present invention consists of the devices andcombination of devices, which will be hereinafter described and claimed.

In the accompanying drawings the present invention has been shown asembodied in a shoe-sewing machine for uniting the outsole to the welt ofa boot or shoe; but such illustration has been selected merely for thepurpose of describing the invention and its mode of operation, and it isto be distinctly understood that it is in no manner restricted thereto,as it can without substantial change be employed in many other machinesfor operating upon the soles of boots and shoes.

In the drawings, Figure 1 shows in front elevation portions of anoutsole-sewing machine embodying the present invention. Fig. 2 shows aside elevation looking in the direction of thearrow, Fig. 1. View of themechanism shown in Figs. 1 and, 2, certain parts being omitted. Fig. 4is a vertical sectional view taken on the dotted line 0000 in Fig. 1,showing details of the mechanism for actuating the movable gage. Figs.

5, 6, 7, and 8 show details of the gage-actuating mechanism, and Figs. 9and 10 show inverted plan views of a pair of shoes.

Before proceeding to describe the illustrated embodiment of the presentinvention it should be stated that it is now the custom in uniting theoutsole to the welt'of a boot and shoe of the type hereinbeforementioned, having soles which extend varying distances from the upper,to place the line of stitches at varying distances from the upper or theFig. 3 is a plan edge of the last in the shoe corresponding to thevariation in the extension of the sole, and to secure this result theshoe must be moved in and out during the process of stitching toward andaway from the path of movement of the needle, the shoe being guided by agage which bears against the side of the lasted upper near the welt.

In the drawings, A represents a portion of the frame of the machine,upon which are supported vertical standards A, (one only being shown,)in the upper ends of which is mounted a shaft B, carrying a cam B. Upona stud a,secured in the frame A, is mounted the needle-segment a,carrying a needle a, and fixedly secured to the frame A and projectingoutwardly and upwardly therefrom is the fixed work support and gage 0,formed with an aperture 0 for the passage of the needle and awl, theforward end of which is arranged to bear against the upper of the bootor shoe while the outsole is being sewed to the welt along the shank andaround the toe and inner ball portions and forming the fixed gage.Mounted to reciprocate horizontally in a guideway D is a feed-slide D,which at its inner end carries the upwardlyextending standard d,supporting a stud (1', upon which is mounted the awl-segment (1 carryingthe awl (i The horizontal reciprocations of the slide D are imparted bya lever E, fulcrumed upon a stud e and having a grooved arm c, engaginga block 6 pivotally mounted upon a lever 6 pivotally connected to theupper surface of the feed-slide D, the arm 6 carrying a cam-roll aengaging the cam-path in the cam B.

The machine as above described may be and preferably is constructedsubstantially like the well-known Goodyear outsole-stitcher,and itsconstruction and operation are familiar to those skilled in this art,and therefore a further description herein is deemed unnecessary.

In the machine of the drawings the auxiliary or movable gage 1 isadjustably mounted by a set-screw 2 to the upper end of a lever 3, whichis fulcrumed upon a stud 4, carried by an arm 5, projecting upwardlyfrom a base 6, secured by bolts 7 to the front of the frame A along thefront side of the guideway D. The movable gage 1 is arranged to be movedin and out toward and away from the path of movement of the needle andawl by the rocking of the lever 3 about its fulcrum 4, and in order thatthe said movable gage when in its retracted position may have itswork-bearing face in substantial alinement with the work-bearing face ofthe fixed gage C the fixed gage O is cut out, as shown at 8, and the endof the movable gage 1 is out out, as at 10, forming a projection 11.,which when the movable gage 1 is retracted enables the end of the fixedgage O and the movable gage 1 to fit together, as shown in Fig. 1, thusbringing the work-bearing faces of the fixed gage C and the movable gage1 into alinement with each other and to a certain degree enabling themovable gage 1 to strengthen and support the work-supporting table 0 orfixed gage against the downward thrust of the needle as it passesthrough the work.

Any suitable means may be provided to rock the lever 3 about its fulcrum4 to advance and retract the movable gage 1; but in the machine of thedrawings the said lever is arranged to be rocked in one direction,preferably, to retract the gage 1 by means of a spring 12, secured byscrews 13 to the front of the machine, the upper end of which bearsagainst the lever 3 above its fulcrum 4, and said lever 3 is arranged tobe rocked about its fulcrum 4 for the purpose of advancing or projectingthe movable gage 1 beyond the fixed gage O by means of a cam andconnecting mechanism, which will now be described.

Projecting downwardly from the base 6 is a bearing 14, in which issecured a stud 15, supporting a horizontally-rocking lever 16, one endof which carries an adjustable screw 17, which bears against the lowerend of the lever 3, the other end of the lever 16 engaging a cam 18,which when rotated by mechanism which will be hereinafter described,

either positively moves the lever 16 about its fulcrum 15 to rock thelever 3 and advance the movable gage or permits the spring 12 to rockthe lever 3 and the lever 16, retracting the gauge 1, it beingunderstood that the spring 12 maintains the lever 16 always in contactwith the cam 18.

As shown in the drawings, the cam 18 is a double cam, and its shape issuch that it will in each half-revolution move the lever 16 so as toadvance the gage 1 to its extreme outward position and permit said gage1 to be forced by the spring 12 to its extreme inward or retractedposition, and said cam 18 dependent upon the direction of its rotation,is adapted to actuate the gage 1 for either right or left shoe.

As before suggested, there is provided suitable automatic mechanism forrotating the cam 18, and the starting of such mechanism is under thecontrol of the operator, whereby he can start such mechanism intooperation either to rotate said cam to advance the gage 1 from itsinward or retracted position to its extreme advanced position or torotate the said cam to permit said gage to be retracted from itsadvanced to its retracted position, such mechanism being arranged tostop the rotation of the cam 18 with the gage 1 in its retractedposition or in its advanced position until the point is reached insewing the sole to the welt which renders it necessary to move the gage1 from either of these positions, and the mechanism for turning the cam18 is also constructed and arranged whereby said cam may be turned ineither direction, according as the operator may be sewing a right orleft shoe.

In the machine of the drawings the cam 18 IIO is mounted to turn about ashaft 19, the upper end of which is threaded, as shown at 20, andsupported in an arm 21 projected from the base 6, it being held in sucharm 21 by means of a nut 22 engaging the upper threaded end, as clearlyshown in Fig. 4 of the drawings. The cam 18 is given a step-by-stepturning movement on the shaft 19 by means of ratchet-wheels 23 and 24,having their teeth formed in opposite direction, as shown, and saidratchet-wheels and the cam 18 are secured to turn together about theshaft 19 by pins 25, whereby their relative positions are alwaysmaintained. The ratchet-wheels 23 and 24 and the cam 18 are held on theshaft 19 by means of a splined washer 26, which is placed on said shaftbeneath the cam 18 above a spring-washer 27 and nuts 28, whereby the camand ratchet-wheels are held with some friction between saidspring-washer 27 and the under side of the bearing 21, but permitted tobe turned on the shaft 19 by the pawl mechanism which will now bedescribed.

It is well known to those skilled in the art that the feeding of theshoe as the stitching progresses around the sole is performed by the awldiwhich, as before stated, is mounted in a segment 01 carried by an armd, supported on the feed-slide D, which feed-slide is horizontallyreciprocated, imparting a step by-step feeding movement to the shoe.

In the machine of the drawings the pawls which engage the ratchet-wheels23 and 24 are carried by the feed-slide D and partake of thereciprocations of said feed-slide and are preferably constructed andarranged as follows: Pivotally mounted at 29 upon a support 30, securedby. screws 31 to the end of the feed-slide D, is a tubular sleeve 32, inwhich is arranged a vertically-movable pawlcarrying plunger 33, which atits lower end carries pawls 34 and 35-, arranged at diametricallyopposite points from each other and in difierent horizontal planes, thepawl 34 being in a plane to engage the ratchet-wheel 23 when turned tothe front, as shown in Fig. 4 of the drawings, and the pawl 35 being ina plane to engage the'ratchet-wheel 24 when turned to the front. Theplunger 33 rests upon a spiral spring 36 within the tubular sleeve 32,which spring normally holds the plunger 33 in an elevated position for apurpose to be hereinafter described.

The plunger 33 is held with either the pawl 34 or the pawl 35 turnedtoward the front by a pin 37, which is carried by said plunger below thesleeve 32 and which is arranged to engage a groove 38, cut in the lowerend of said sleeve.

By depressing the plunger 32 against the tension of the spring 36 untilthe pin 37 clears the groove 38 said plunger may be turned to bringeither the pawl 34 or the pawl 35 in position to engage their respectiveratchetwheels.

By an inspection of Fig. 4 of the drawings it will be noted that thepawls are substantially one-half the thickness of the ratchets, and thatthe spring 36 normally holds the plunger 32 in an elevated position, sothat the respective pawls engage the upper half of their respectiveratchets. Each ratch et-wheel is provided with four stops 8, s s and sand t, t t and 25 which project beyond the face of the ratchets and areformed with a long inclined surface of such a length that whenever apawl reaches a stop, the recipro cations of said pawl being less thanthe length of the inclines formed on the stops, the continuedreciprocations of the pawls will impart no movement to the ratchets, andtherefore no movement to the cam 18, thus leaving the gage 1 in whateverposition it may have been moved to until the operator again desires tomove the said gage.

The stops 3', s s and s and t, t t and t are substantially one-half thethickness of the ratchets 23 and 24 and. are placed along the upper edgethereof in the path of move ment of the pawls, so that in order to againcause the reciprocations of the pawl which may be to the front to engageand rotate its ratchet the plunger 33 must be depressed to enable thepawl to engage said ratchet below the stops. The pawls arenormallypressed toward the ratchets by means of a spring 39, which isfixedly secured to the end of the plate 40 and which at its lower endbears against the tubular bearing 32, below its fulcrum 29. Bydepressing the plunger 33 against the tension of the spring 36 the pawlwhich may then be at the front and in contact with one of the stops ofthe ratchet-wheels 23 or 24 is brought below said stop and the spring 39forces it forward to engage the ratchet wheel below said stop.

For the purpose of depressing the plunger 33 there is provided in themachine of the drawings a lever 41, pivotally supported at 42 on an arm43, projected from the tubular bearing 32, which lever preferably hasaprojection 44, resting upon the upper end of the plunger 33 or a diskor head carried by said plunger, the opposite end of said lever 41extending outwardly and being projected upwardly, as shown at 41,whereby it is in convenient position for the operator to engage the sameand by a downward movement thereof depress the plunger 33.

For the purpose of maintaining the lever in proper position withrelation to the head of the plunger 33 there are providedupwardlyprojecting'arms 46 on the tubularbearing 32, between which thelever 41 projects.

From the foregoing description it will be clear that according as thepawl 34 or the pawl 35 may be turned to the front the cam 18 will beturned from right to left or from left to right to actuate the movablegage 1 for positioning either a right or a left shoe.

Assuming that the ratchet 23 is engaged by the pawl 34 when sewing aright shoe, it will be noted that the cam 18 will be turned from theposition shown in Fig. 7 from right to IIO left, and when the pawl 35engages the ratchet 24 the cam 18 will be turned from left to right whensewing a left shoe.

In Figs. 9 and 10 are illustrated, diagrammatically, plan views,inverted, of the soles of a pair of shoes, with the line of the uppersindicated by dotted lines, showing that the edge of the sole and Weltproject beyond the upper varying distances, the projection beinggreatest at the outer ball portion of each shoe, as in theBaltimore-edge shoes hereinbefore referred to.

In sewing shoes of the character indicated the auxiliary movable gagewill be brought into operation while the sewing progresses along thatportion of the sole, or substantially so, included between the pointsmarked w and 10 and o and t and while sewing the remainder of the solethe auxiliary gage remains in its retracted position.

It will be noted that the cam 18 has two low points marked 13 and 19;also two high points marked 19 and p and that there is a short rise fromthe points 13 and p to the points 19 and p and a long gradual declinefrom such points 13 and p to the points 19 and 19, thus imparting to theend of the lever 16, which rests on said cam, either a quick outwardmovement and a slow return movement or a slow outward movement and aquick return movement, accordingly as said cam is turned to the right orleft.

Assuming that the operator is sewing a right shoe and that the parts arein the position shown in Figs. 4, 5, 6, and 7, or substantially so, withthe pawl 3-1 engaging the stop 3', at which time the low part 19 of thecam 18 will be to the front and the movable gage 1 in its retractedposition, the operator now positions the shoe as shown in Fig. 9, withthe toe of the shoe pointed toward the right, and begins the sewing atthe rear of the shank of the shoe on the outer side thereof,substantially at the point marked w, and while sewing along the shank orfrom w to w the shoe is held against the fixed gage, and the movablegage remains in its retracted position, as shown in Figs. 1 and 2 of thedrawings. During the sewing of the shank part indicated the pawl 34 hasremained in contact with the stop 5'', imparting no movement to theratchet 23 and the cam 18; but as the sewing reaches the point 10 andproceeds from such point to the widest part of the projecting edge ofthe sole or to it becomes necessary to bring into operation theauxiliary gage 1 to move the shoe outward in order to position theprojecting edge of the sole in proper position relative to the path ofmovement of the needle, so as to position the stitches of the seamproperly with relation to the upper.

It will be noted that from the point w to the point 10 there is anabrupt outward curve from the shank portion of the sole to the widestpart of the projecting edge. When the point w is reached, the operatorbrings into operation the gage-actuating mechanism by depressing thelever 41, thus depressing the plunger 33, and permitting the pawl 34: toengage the ratchet-wheel 23 below the stop 3, and the step-by-steprotation of the ratchet 23 by the reciprocations of the pawl 34: turnsthe cam 18 from right to left, bringing the high part 19 of said cam tothe front, and rocking the lever 16 moves quickly outward the auxiliarygage 1. The turning of the ratchet 23 brings the stop 3 in position toengage the pawl 34:, at which time the turning of the ratchet 23 willstop, with the high part 19 of the cam 18 in front and the auxiliarygage 1 in its extreme outward position, thus positioning the shoe sothat the stitches will be placed at the greatest distance from the upperat the widest part of the shoe-sole. Assuming that the sewing hasprogressed from the point 10' to the point 102 during this outwardmovement of the auxiliary gage and that the point ufiapproximatelyrepresents the beginning of the widest part of the projecting edge ofthe shoe-sole, the sewing will then proceed along the widest part withthe shoe guided by the movable gage in its advanced position, and itremains in this position until the sewing has been completed along thewidest part of the shoe-sole approximately to the point marked 10 Itwill be noted that from the point 20 to the point 0 0 there is a gradualnarrowing of the projecting edge of the shoe-sole,and when the point 20is reached the operator again brings into operation the actuatingmechanism for the movable gage by again depressing the lever 41 andpermitting the pawl 34 to engage the ratchet 23 below the stop 8 and thereciprocations of the pawl 34 turn the ratchet 23 and the cam 18, movingthe high point 132 away from the front and bringing the point p to thefront, the shape of the cam being such that the gradual decline from thehigh point p to the low point p permits a gradual inward movement of theauxiliary gage 1, which movement takes place while the sewing progressesfrom the point 1.0 to the point 10 at which time the gage 1 will havereached its retracted position, and the stop 5 coming in contact withthe pawl 34, stops the further turning of the ratchet 23 and the cam 18,and the sewing then progresses with the shoe guided by the fixed gagefrom the point 10 around the toe along the inner ball portion to therear of the inner shank portion. In sewing a left shoe the pawl 35 willbe turned to the front and brought into engagement with the ratchet 24:and the reciprocations thereof will cause a turning of the ratchet 24from left to right, thus turning the cam 18 from left to right.

The left shoe is positioned in the same manner as in sewing a rightshoe, that is-with the toe of the shoe turned toward the right and thesewing begins at the point 4) at the rear of the inner shank portion, atwhich time the pawl 35 will be in engagement with the stop if of theratchet 24, and the auxiliary gage will be in its retracted position.The sewing thus progresses from the point t along the inner shankportion, the inner ball portion, and around the toe until approximatelythe point o is reached, at which time there is a gradual widening of theprojecting edge of the shoe-sole. It is therefore necessary that themovable gage be brought into operation to move the shoe outwardgradually while the sewing progresses from the point 11 to approximatelythe point 02 at which point the widest part of the projecting edge ofthe shoe-sole begins. The operator therefore depresses the lever 41 andpermits the pawl 35 to engage the ratchet 24 below the stop t, and whilethe sewing progresses from the point '0' to the point r the rotations ofthe pawl 35 will turn the ratchet 24 from left to right, turning the cam18 from left to right, and gradually bringing the high part 19 of thecam to the front, thus gradually advancing the movable gage to itsextreme outward position, and as the point 0 is reached the pawl 35comes in contact with the stop 25 thus stopping the turning of theratchet 24 and the cam 18, with the high part of the cam 19 in theforward position and thegage 1 in its advanced position. While the partsare in this position with the gage 1 moved out, the stitching proceedsfrom the point e to approximately the point 12 during which time thegage and its actuating mechanism are at rest. As the point o is reachedit is necessary that the movable gage be quickly retracted in order topermit the shoe to move quickly back as the sewing progrosses from thepoint '0 to the beginning of the outer shank portion or to the point 2:The operator therefore again depresses the lever 41 and permits the pawl35 to engage the ratchet 2 1 below the stop 25 and while the sewingprogresses from the point 11 to the point o the reciprocations of thepawl 35 will turn the ratchet 24, turning the cam 18, bringing to thefront the low part 19 of said cam, thus permitting the spring 12 toquickly retract the gagel to its extreme inward position. At this timethe stop 15 will come in contact with the pawl 35, thus stopping theturning of the ratchet 24 and the movement of the cam 18, and the sewingprogresses along the outer shank portion with the gage retracted.

In describing the operation of my improved auxiliary gage I have assumedthat it is employed in sewing what is known as Baltimore-edge shoes,wherein the sole projects a greater distance upon one side than on theother; but it is obvious that both sides of the shoe-sole may projectuniformly, in which case the auxiliary gage will be brought intooperation while sewing along the inner ball portion of the shoe as wellas along the outer ball portion.

It will be noted that by arranging the mechanism of the auxiliary gageso as to be thrown into operation by the operator it is adapted foremployment with all sizes of shoes, as it remains at rest until theoperator desires that it shall move in or out, as the case may be, sothat no matter what the length of that portion of the sole which isbeing stitched while the gage is in its retracted or its advancedposition may be it may remain in such position until said portions ofthe shoe-sole shall have been stitched, and whenever it becomesnecessary to either advance or retract such gage while the sewingproceeds from a narrow part to a wide part of the shoe-sole or from awide part to a narrow part such movement is automatically produced.

Having thus described the construction and mode of operation of myinvention, I claim as new and desire to secure by Letters Patent of theUnited States 1.
